	I have a similar problem on my 99 2.5L TJ -- except that it only happens at idle when the AC is turned on. When I'm driving, accelerating, or decelerating, it sounds ok. When I come to a complete stop, it squeaks like crazy. Sounds like something vibrating against something more than a loose belt. I'd be interested to see what fixes yours.

	I was referring to the micanic who always suggests changing the most expensive units first. Yes remove the belt and rub the engine with it off but don't run it for long. Snow "L.W.

	lets see how long it takes for a engine to hit op. temp on a 70 degree day 10 minutes maybe at a idle, more than enough time to figure out if a pulley is bad or a fan clutch long before it needs a motor from overheat see, we will run a engine with the belt off and not just spray a mechinac in a can fix like you might so we can correctly fix the issue but hey thats just me Snow wrote: take the belt off and start and run the vehicle if it's still there then> > there is a good chance it's the fan clutch> And while its off, you can end up over heating the engine as you will have> no coolant flow, but I'm sure someone will install a engine for you.

Oh and with the belt off, it will heat up faster as the water pump won't be turning. Second, every stealership I have ever been to all have and use belt dressing to get rid of squeaks. The silicone spray is much better and wont leave sticky residue (safe for aircraft use to). Snow...
